Dual-Band GNSS Anti-Jamming Antenna B1/L1/E1+B2a/L5/E5a 8+8 CRPA 7+7 Interference Suppression Built-in Receiver

Product Introduction

            The YT240 Dual-Band Anti-Jamming Antenna is an 8+8 element GNSS array that receives 8 channels of B1I, B1C, L1, E1 and G1 signals together with 8 channels of B2a, B2b, L5, E5a and E5b signals, applies anti-jamming processing on both bands, and combines them into a single RF output. It delivers 7+7 interference processing across 10 frequencies and 4 satellite systems, effectively rejecting wideband, narrowband, multi-tone, single-tone, sweep and pulse suppression-type interference on the B1I/B1C/L1/E1/G1 and B2a/B2b/L5/E5a/E5b bands.

          L1 and L5 offer identical anti-jamming performance: ≥110 dB against a single interference source, ≥95 dB against three, and ≥85 dB against seven, with an antenna output power of -50 to -70 dBm. The unit integrates a receiver, runs on +24~32 V with ≤32 W power consumption, measures Φ240×42 mm, and weighs ≤1.6 kg including the receiver. It uses a J30JM-15ZK power/I-O connector and a TNC-KF RF output, operates from -40℃ to +70℃ (storage -40℃ to +85℃), and is finished in grey TS96-71-586 FS36375. Ideal for UAV, autonomous driving, surveying, marine and precision agriculture applications requiring high-precision positioning.

Key cores 

1. True dual-band anti-jamming: Independent anti-jamming processing on B1/L1/E1 and B2a/L5/E5a, combined into one output — a single antenna covering both bands.
2. High suppression capability: Identical L1 and L5 performance — ≥110 dB single-source, ≥95 dB three-source, ≥85 dB seven-source.
3. 8+8 array · 7+7 interference processing: 10 frequencies across 4 systems with simultaneous 7+7 interference handling for stable positioning in multi-source environments.
4. Integrated receiver: Antenna and receiver in one housing, reducing external hardware and simplifying system integration.
5. Full suppression-type rejection: Rejects wideband, narrowband, multi-tone, single-tone, sweep and pulse interference.
6. Compact and lightweight: Φ240×42 mm and ≤1.6 kg including the receiver — easy to mount on UAV and vehicle platforms.
7. Low power draw: +24~32 V input with ≤32 W total consumption.
8. Industrial-grade reliability: -40℃+70℃ operating and -40℃+85℃ storage, grey FS36375 durable coating.
9. Standard interfaces: J30JM-15ZK power/I-O connector plus TNC-KF RF output for easy installation and maintenance.
